Confess your sins to God. Ask the Holy Spirit to reveal areas of weakness. Forgive all who have offended you and ask for forgiveness from those who you may have offended (Mark 11:25; Luke 11:4; 17:3, 4). Surrender your life fully to Jesus Christ and reject the worldly desires that try to stop you (Romans 12:1, 2).
Prepare yourself physically. If it’s a food fast, consult your doctor prior to fasting and explain what you plan to do. This is especially important if you take prescription medications if you have a chronic ailment. Some people should never fast without professional supervision. While you fast, limit your activity and exercise only moderately. Take time to rest. Be ready for some physical discomforts especially early in the fast. Your body is detoxifying and you may be having withdrawal from caffeine and sugars. You may have headaches; hunger pains and even become irritable! Spend time listening to praise and worship, pray as often as you can throughout the day. Get away from the normal distractions as much as possible and keep your heart and mind seeking God’s face.
End your day slowly. Don’t overeat when the time comes to end your fast. Begin eating solid foods gradually and eat smaller portions or snacks until your body is re-accustomed to eating solid foods.
